l `The Schedule reterred to these Letters P atent and making part ofthc. same v Beit known 'that I, ALBEET RUSSELL, of-Newburyport, inthecounty of Essex-and State'of Massa-v chusetts, have invented a `new anduseful 'Improvemeut in Machinery for Operating the Windlass of aNavigable Vessel; and I do hereby declare the same tobe fully described,in therfollowiiig Specification and representedin the accompanyingdrawing, ot' which-- Figure 1 is a topjview, and y Figure 2, a.sidefjelevation of'a'I win'dlass vprovided :with my invention, henatureof which 4consists in a special arrangement and'eombination, in themanner as setforth, of two 'disconnected brakes orl operative leverswith the pawlLcases of the windlass'. In the drawing-. Y i A denotesthewindlass; 4B and C, its two` pawlf-cases or working pawl-carriers; `and,i j,

D D, its ratchets, constructed and applied together in' the usualmanner, thefsaid pawl-cases being `arranged in the'eommon way, with apost, E,between them.

Above the deck or platform F,disposed over the main deck G' and over thepawl-cases, I arrange, in

The shorter arm of" each lever is slotted, as shown at a, to receive oneof the connection-rods b I1 of the .pawl-cases, the lever beingconnected to such rod by apio, c, going through both.

Byseamen takinghold ofthe longe-x` arm of each of 4the brakes or levers,and rnoving `it-up and down, each pawl-case will have a reciprocating orvibratory move- Y the rods, is employed. Or instead ofsuch, two levers,

connected by an intermediate lever and supported by vbratory posts, areused, such beingjasshown in the patent No. 16,000, 'rautedNovemb'er-,1856, to

Christopher Amazeen.

l"The advantagesoi' two independent brake-levers,

one to each pawl-case, as represented in the drawing, are that suchadmit of the windlass being-worked b v one of the brake-levers withoutthe other being moved I oriutert'ering iu any way with the operation ofthe -first.V rIhey also admit of both pawl-cases being worked in thesame direction at once, thereby enabling the .operatives to exert theirpower with better ormore useful effect, There are other importantadvantages possessed by the employment of independent levers withseparate fulcrums, as it admits-of longer levers being used; These canwell be employed when two levers are connected by a. third, as in theAmazeen windlass. i

I, therefore, elaim The two disconnected levers orjbrakes, combined vandarranged, as explained, with the win'dlass and its ratchets and theirpawl-cascs, the whole` 4being to operate substantially as specified.
